Lina Moze has been operating her antiques store, Senovinis Antiques, for more than a year now, after working in the retail industry for over twenty years. She is renting space in an antiques mall where there are other antiques dealers who have space from which they sell their inventory of vintage/antiques items. Lina has acquired some good contacts since locating in the mall, many of whom have provided her with information on where to find new merchandise to replace those she has sold, and specialty services such as furniture repair and restoration. She also frequents flea markets, country auctions, estate, and store closeout sales for bargain opportunities. Business is beginning to pick up, mainly by word-of mouth, personal contacts and casual walk-ins. Record keeping is currently just using spreadsheets and paper files on inventory and transactions. She wants to raise her business to a more efficient level, by better keeping track of inventory items, suppliers, and customers. Currently, her only employees are her husband, Filip Moze, and their daughter, Roze Moze, who both help out on a part-time basis. If her business expands sufficiently, she would like to hire her daughter full-time, and perhaps hire an additional part-time assistant. Roze has been taking courses in computer-based information-systems at the local university and she suggested that the business could improve their revenue, lower their cost of operations, and improve customer service and satisfaction by implementing an information system that effectively and efficiently supports her business.
